Cloverleaf components are a type of highway interchange that consists of loops, ramps, onramps, and exitramps. Loops are curved sections of road that allow vehicles to turn around and go in the opposite direction. Ramps are sections of road that connect two highways at different elevations. Onramps are sections of road that allow vehicles to enter a highway from a lower-level road. Exitramps are sections of road that allow vehicles to exit a highway onto a lower-level road. Together, these components form a cloverleaf interchange, which is a type of highway interchange that allows for efficient traffic flow.
